Made an account just to say thank you, that was pretty informative. I've tried gamemaker and had the exact same experience, I wanted more, and then it hit me that their GML doesn't work for anything outside their software, which made me feel like I wasted so much time learning their language(and dropping so much money into it). While Unity, or Godot for example can use languages that you can use outside their software or for stuff other than games.
Wanted to try 001 Game creator specially since I'm seeing it on a Humble Bundle but it seems like I better spend my time somewhere else.
